I don't know about quinoa, but my old neighbor had a good time growing amaranth, which is its more heat-tolerant cousin. Do expect it to leave you with some volunteers though. I don't think quinoa would do too well where i live but it might be fine up in indiana, and growing its probably not too different? But I'm not sure.

She wouldn't grow huge amounts, a paper grocery sack or so, but it seemed prolific and easy. Plus, its beautiful, with the huge red flowers and edible leaves (though I never actually ate them, I don't know if she did- I didn't want to take enough for myself from her garden. My guinea pig ate it though!).

I don't think either of these seed plants actually need winnowing like the actual grain plants.

Millet is easy as heck too though, I had some sprout from my bird feeder...I just let it seed and hoped the birds ate that too.

I grew quinoa, but primarily for the edible greens and immature seedheads, which I braised. I let some go to seed, but even though it didn't need winnowing, it was pretty labor intensive. Amaranth seed is easier to collect, but so small you'd need to grow a massive amount to get a reasonable harvest. And Lycophyte is right, quinoa does better than amaranth in cooler climates. It was super easy for me to grow in Portland. Here again is the link that provides great info: http://www.saltspringseeds.com/scoop/powerfood.htm

We had quinoa in the garden this year. They seemed to be doing great all summer long and got really big and had the seeds all over the top and everything. Then I forgot to look up what we're supposed to do to harvest it and...I think we waited too long because they just kind of died. And, we also moved to a new house so we will have to start all over on the garden next year. But we're going to try quinoa again!

Also, what?! I could have eaten the greens and braised the seedheads? I am a gardening FAILURE! But not next year :)
